Impression library not working on Jessie

[hardillb]

Installed via the one line curl/bash script.

Fully updated Jessie install (yes, I know i should upgrade, but it's the pi zero I had to hand that I've been using with the inkey pHat & the script does say it's supported...)

Running any of the examples/7color code gives the following error:

$ ./clear.py 
Traceback (most recent call last):
  File "./clear.py", line 14, in <module>
    inky.show()
  File "/usr/local/lib/python3.4/dist-packages/inky/inky_uc8159.py", line 365, in show
    self._update(buf.astype('uint8').tolist(), busy_wait=busy_wait)
  File "/usr/local/lib/python3.4/dist-packages/inky/inky_uc8159.py", line 320, in _update

    self._spi_bus.no_cs = True
AttributeError: 'SpiDev' object has no attribute 'no_cs'

I've tried running with python 3.4.2 and 2.4.7

It looks like the required version of python3-spidev is installed:

aptitude show python3-spidev

Looks like no_cs was added in 2016 so after the 20150907 build available on Jessie.

Happy for this not to be fixed for Jessie if it's not simple, the right answer might be to say that Jessie is not supported.

Yeah I think supporting Jessie now might be a bit of a Stretch, Buster! I'm already in such a Squeeze I'm getting Wheezy

Sorry.

Might be worth grabbing the source, editing out the no_cs and seeing if it works for you. All my Pi's are packed in moving boxes to say nothing of digging out something so ancient. It might be possible to trap this error and just skip "no_cs".
